I've bought Geneva Scenery and i had installed previously the demo version.
When i tried to activate the scenery nothing happened. No message and the buildings continued to disappear after five minutes.
I uninstalled and reinstalled, but then I was no longer able to start flights in LSGG.
I've already tried everything I found on the forum in LSGG section as a possible solution, but I'm still unable to load the scenary after installation and the following message appears when starting FS9: Can't install esellerate engine! Addon manager will not run.
